SPECIFICATION `forming part of Letters Patent No; 381,109, dated Aprill 17, 1888.

l Application filed `September 5,1887. Serial No. 248,884. (No model.) i

To all whoa/z."r lit may concern: l.

Be it known that I, ALEXANDER T. BROWN, of Syracuse, county of Onondaga, in the State of New York, a citizen `of the United States,

have invented certain new and useful Improvements in Air-Guns, of which the followying 1s a specification, reference being had to the accompanying drawings, in which i Figure l is a longitudinal section of the gun vzo discharged. Fig. 2 isa like lsectionzof the same ready to be discharged. Fig. 3- is adetail of the piston. Fig. 4 is al plan view of the feed-aperture opening Vinto the magazine; Fig. 5, an enlarged section of the rear end of the I5 barrel. i My invention relates to .that class i of airgnns in which a springactuated piston forces the air in areceivingchamber against the projectile in the barrel; and my Objectis to pro` 2O duce a magazine or repeating air-gun provided wlth a reservoir to receive a number of pro-I jectiles which are automatically and in regular sequence fed into the barrel.

It consists in the several novel features of A construction and operation and combinations j of elements, which are hereinafter described,

, and which are speciiically claimed herein.

It is constructed as follows: A is the stock, provided with a fore-end, 1, inwhich I cut 3o a longitudinal slotway, 2, forward from the v breech-block.

B is'the barrelmounted upon the fore-end, provided with the regular bore and also with another bore, 3, opening out at the rear end '3'5 of the barrel and also communicating with-the regular bore by the 'opening.4.' This bore 3 constitutes the magazine; Upon the top of 1 the barrel, above the front end of the magazine,I I secure the .block ,v which may also be the y4o rear-sight block, and in the front end ,thereof I insert a transverse pin, 6, and drill a hole,

7, vertically and openingvinto the pin-hole. This .pin is also provided with the diametric hole shown at 8, and the magazine'opens out through the top fof thev barrel directly under the pin 6, so that lwhen the pin is turned so that the hole through it Yis-vertical a shot or projectile insertedl into the hole 7 ypasses through yinto the magazine, and then when I 5o tnrnthe pin around; so that the hole'8 is lhorizontal, (by the rod 9 connected tothe pim) v of the piston-stem, and its rear end is of sub-.I` stan'tally the form shown 'in the drawings.

the magazine is closed air-tight, so that no com pressed air can escape therefrom through the feeding or lling mechanism. i Between the barrel and the stock, and con- 5 5 nectedto both by anair-tight joint-I placera, I, v

single tube, 10, the frontend of-which'constitutes the receiver'orair-compression chamyber 11, and'in its rearward lowervsile I fcuta longitudinal slot, as is clearly illustrated ,in the drawings, to receive the stemopf the pis-y 'tonv C. 'Ihispistonconsi'sts of a head,12, i

provided with suitable flexible packing, to fit the bore of the receiver, v a body, 13, provided with4 a longitudinal slot, 14, andv aty its rear end withhan offset stem, 15, which is 'constructed with a flat front, a convex back, 16,'and flanges f 17, of proper width to vfit in theslotway 2in, .thefore-end.- In the front end of the slot way 2 I secure the holder '18,which hold'soneA 7o end of the rubber band v19 vthe other end off .which is held upon the convexity ofthe stern of the piston.Y In rthe fore-end I also bout a f vertical slot opening rinto the slotway 2, and in this slot -I mount the lever or guard 20 upon a pivot-pin, 21.` The front lend of thisv lever passes upy through' the fore-end, and when the gun is not cocked engages with the front facey The stock yis recessed to receive the searspring 22 and trigger 23, the frontend of v l v which projects into the ,slotway in thejforev end, and the lip shown thereon engages with the front face ofthe piston-stem,whcn thepis-r tonis drawn back,by throwing the rear end of` the lever forward, when` the front\ end l thereof carries or draws the pistonfloackwardy until the trigger engages'with the piston-stern.` Inithe front endfof. the pistony I secure a rigid projectile-starting rod, 24..

In Fig. 4I show a 'countersunk cavity in the bottom of th'ebore of the barrel to receive y. l Y

a spherical projectileand holdv it fronslip55%,4

ping or rolling in this bore, and also arecessg 5 4inthe top of ythis bore, in which Is'ecure'a spring, 25, therear end of which bends'upward I.

intoitheopening 4,co nnecting the barrel-bore vwith the' magazine, and also the starting-.rod 1 f" roc jectile out from the countersink and through under the spring; and just as this is accomplished the enlarged part of the rod will pass under the spring and hold its rear end up, as shown by the dotted lines, as a stop to prevent another projectile from entering the bore of the gun before the rod is withdrawn.

What I cla-im as my invention, and desire to secure by Letters Patent, is-

l. The combination, with the trigger-guard lever pivoted in the fore-end' and extending upward and engaging directly with the piston in the receiving-chamber forward of the stock, of the piston having a solid head, a slotted body, and a rearward and downward stem, and the spring connected to the piston-stem and to the fore-end, and the trigger, substantially as shown and described.

2. In an air-gun, a barrel provided with a bore, in combination with a magazine wholly within the barrel and communicating with the bore at one end, and at the other end having a loading-aperture opening out' through the barrel,provided with a transversely-rotating perforated bolt adapted to close the loadingaperture air-tight, substantially as described.

3. The combination,with the barrel having a magazine wholly within the body thereof and the magazine communicating with its bore and having a rotating closer in the loadingaperture, of a receiver between thestock and barrel and in line therewith, a piston Within the receiver, having a solid head in which a starting-rod is secured, a slotted body and a stem upon the rear end, and a springr connected to the piston-stem and fore end, substantially as described.

4. The combination, with the barrel, the magazine whollywithin it,and the opening connecting the magazine tothe bore,of a startingrod secured in the piston-head and having an enlargement of its body adjacent to the pistonhead, substantially as described.

5. In combination with a barrel having a magazine wholly within it connected to its bore, a receiver between the stock and barrel, hav-y ing a longitudinal slot for part of itslength, a

Vpiston fitting therein and having a stem extendingV downthrough the slot, a spring connecting the piston-stem to the fore-end, and a trigger-guard pivoted in the fore-end and extended upward 'and engaging directly with the piston, substantially as described.

6. A pivoted trigger-guard extending upward and engaging directly with the body of the piston in the receiving-chamber, in combination' with the piston, substantially as described.

In witness whereof I have hereunto set my hand this 22d day of August, 1887.
